Understanding the emergence of agriculture and its relationship with the regional cultural background is crucial for comprehending the development of societies. This study combined detailed phytolith analysis with archaeological and historical data and examined Late Neolithic sites in the inland mountainous area of Fujian. The results revealed the presence of various rice phytoliths from the Niubishan to Maling period (5300–3800 cal BP), indicating that rice cultivation occurred in this region at least 5000 years ago. Furthermore, the earliest millet phytoliths emerged in the Upper Niubishan Culture layers 4500 years ago. These findings provide a comprehensive understanding of the agricultural development in this region. This study suggests that the emergence of rice and millet in the southeastern mountainous areas of China may be linked to interactions between prehistoric cultures in different regions. The initial emergence of rice at approximately 7500 cal BP likely spread from the lower Yangtze River along the coastal route. Between 5500 and 3500 cal BP, the gradual opening of land routes facilitated the southward dispersal of agriculture from the middle and lower Yangtze River, creating interconnected land and sea routes. This integration possibly led to the formation of a mixed rice-millet agricultural system that spread to Southeast Asia. Additionally, environmental factors, such as early to mid-Holocene sea level rise and mid to late Holocene drought, appear to have played a crucial role in the emergence and spread of agriculture in this region. Overall, These findings provide significant insights into the emergence, development, and dispersal of prehistoric agriculture and its relationship with cultural exchange and environmental changes in this region.</div></div>","PeriodicalId":48150,"journal":{"name":"Journal of Archaeological Science-Reports","volume":"61 ","pages":"Article 104975"},"PeriodicalIF":1.5,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143148143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"历史学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Arguably, identifying basic structures in abstract decoration by applying formal methods is a useful prerequisite for proceeding to well-grounded interpretation of its role in a given cultural context. It may also inform intermediate, middle-range analyses, such as experimental work. We present a new, network-analytical method designed to identify basic structures in decoration, such as relations between decorative elements, the centrality rank of individual elements included in a given pattern or other relational structures hypothesized to be significant to the perceptual and cognitive effects of a pattern. To demonstrate its use and potential, we apply the method to pottery of the Neolithic Funnel Beaker/TRB period in southern Scandinavia (4000–2600 BCE), which exhibits elaborate abstract decoration. While most formal studies of ceramic morphology and decoration in archaeology have focused on typology and chronology, we argue that structures identified using this method can be used to explore the syntax of decorative patterns, which may reflect underlying aesthetic, ideological and social preferences. Applying network analyses to materially static patterns of decoration differs fundamentally from previous applications of formal network theory and modelling in archaeology, and faces different challenges. In addition to demonstrating the former in practice, we address the potentials and problems of this novel application and discuss its relevance in the wider study of material culture.</div></div>","PeriodicalId":48150,"journal":{"name":"Journal of Archaeological Science-Reports","volume":"61 ","pages":"Article 104959"},"PeriodicalIF":1.5,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143148145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"历史学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Utilising FTIR spectroscopy and stylistic analysis, the current study aims to answer those questions by investigating the provenance and physical conditions of the Kerkenes amber specimens. The results of spectroscopic analysis have indicated a Baltic origin for all analysed amber samples from Kerkenes. Moreover, the analysis has also hinted at the heat treatment and subsequent oxidisation of the samples. These findings, when considered alongside decades of archaeological investigations on amber in Europe, confirm that amber supply networks from the Baltic Sea to the Aegean and Black Sea regions exhibited a degree of resilience over time and/or underwent re-establishment during the period of Phrygian dominance in central Anatolia.
